CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,840, dated March23, 1880.

Application filed January 6, 1880.

lb all whom it may concern Be it known that I, REUBEN F. KROHN, ofSunbury, in the county of Northumberland I and State of Pennsylvania,have inw'ented a new and Improved Gar-Oouplin g, of which the followingis a specification.

Figure l is a plan of the device. Fig. 2 is a longitudinal sectionalelevation on line as m, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a simple and effectiveself-coupler whereby cars can be coupled or uncoupled and the linkremoved Without going between the cars.

In the drawings, A represents a draw-head provided with a centrallongitudinal opening, a, in its top, within which is pivoted, on the pin0, the curved latch or tongue B, whose upper surface is flush with thetop of the drawhead and whose under surface curves downward, as shown,and rests on the lug 0 below it. C is a triangular lug, rigidly fixedwith its point forward just within the mouth of the draw-head A, asshown, with the short face of the said lug undercut, as shown at 0,looking rearward. On a parallel line with this lug O, and rearward ofit, in the draw-head A, is rigidly fixed the triangular lug D on thebottom of the said draw-head. This lug D is somewhat lower than the lugC, has its short face undercut, as shown at d, and is set a shortdistance from the lug (J and facing it, so that between the two lugsthere is an opening or socket, f, shaped somewhat like an egg, with anarrow opening, g, in its top for the admission of the coupling-link E.

On either side of the opening a, near the mouth of the draw-head A, andpassing down through the top plate to the lower plate thereof, are thepins F, that serve as guides for an entering link, and may (either ofthem) be also used to hold the link in the event of the breaking of thelug U.

The end of the link E, entering the drawhead between the pins F, will,in coupling, move up the inclined face of the lug C to its highestpoint, pushing up the tongue or latch B in the latter part of itsprogress, and as soon as the end of the said link has passed the tip ofthe said lug O the weight of the tongue or latch B forces it (the link)down through the opening 9 into the socket f between the lugs (J l),whence it is prevented from drawing out by the lug G and prevented frommoving rearward by the lug D.

A car can be uncoupled and the link E removed through the opening a onturning the tongue or latch B back, as shown on the right in Fig. 2,avoiding the trouble and danger of going between the cars for suchpurpose.

Having thus described my invention, I claim as new and desire to secureby Letters Patout-- A car-coupler having the oppositely-concax'ed lugs Oc D d, forming the socket j g, the guides F F, and the rear hingedtongue, B, supported on the more elevated front lug, O, as shown anddescribed.
